Cardiomyopathy, Dilated, 1h

For a general phenotypic description and a discussion of genetic heterogeneity of dilated cardiomyopathy, see CMD1A (115200).

Clinical Features

Jung et al. (1999) studied a German family in which 12 individuals had autosomal dominant CMD characterized by ventricular dilatation, impaired systolic function, and conduction disease.

Mapping

After exclusion of the known loci for CMD in a German family segregating for the disorder, Jung et al. (1999) performed a whole-genome screen and detected linkage to 2q14-q22. A peak lod score of 3.73 at a recombination fraction of zero was found at D2S2339.
